Suspension / Ride Quality Problems

[Yetti]

s'cuse me I didn't catch that you put the stock tires back on in my first read. still the fact remains. I run my stock BFGs at 38 psi in summer and 40 in winter. the ride is great.

Yes the spare tire carrier has been removed.... that makes for a good point... what could I do to counter the fact that the weight is now missing.

The stocks are running like 42psi at the moment...

Howdy again, I guess just as a test to see how much you can do for weight I would see if you can add weight to the bed with something heavy such as old sheet rock or bags of cement to offset the weight difference. I have never weighed a tire so I expect they are heavy, I'm guessing around 100lbs + the tire carrier. also since your climate isn't as cold as Michigan I would drop down the tire pressure to around 35-38 psi. make them all the same. if you see a huge increase in ride quality remove weight a little at a time to see if you can come to a reasonable amout to keep in the truck to get the bounce out. if it comes down to it you might just buy a nice piece of thick diamond plate cut to fit the bed to replace the weight and still look nice.

by the way does yours have air suspension? I am only guessing it does not.

Don't forget that spare is hanging off the rear so it's distance from the center is providing more leverage than the same amount of weight in the bed. To get the same moment of inertia you'll need more weight in the bed.

It's the same thing with sandbags in the bed of a pick-up, the guys that failed high school physics try to keep them near the axle, the guys that know better place them by the tailgate
